Defined in header <wchar.h> struct mbstate_t; (since C95) The type mbstate_t is a trivial non-array type that can represent any of the conversion states that can occur in an implementation-defined set of supported multibyte character encoding rules. Zero-initialized value of mbstate_t represents the initial conversion state, although other values of mbstate_t may exist that also represent the initial conversion state. Possible implementation of mbstate_t is a struct type ho

Usage conditionally-supported type specifier for Fortran language linkage. May be used with function declarations and other external declarations to indicate that the calling convention and name mangling is suitable for linking with translation units written in the Fortran programming language.

Defined in header <stdio.h> int puts( const char *str ); Writes character string str and a newline to stdout. Parameters str - character string to be written Return value non-negative number on success or EOF otherwise. Example puts() with error checking. #include <stdio.h> #include <stdlib.h> int main(void) { int ret_code = puts("Hello World"); if ((ret_code == EOF) && (ferror(stdout))) /* test whether EOF was reached */

Defined in header <wchar.h> size_t wcscspn( const wchar_t* dest, const wchar_t* src ); (since C95) Returns the length of the maximum initial segment of the wide string pointed to by dest, that consists of only the characters not found in wide string pointed to by src. Parameters dest - pointer to the null-terminated wide string to be analyzed src - pointer to the null-terminated wide string that contains the characters to search for Return value The leng

Defined in header <threads.h> thrd_t thrd_current(); (since C11) Returns the identifier of the calling thread. Parameters (none). Return value The identifier of the calling thread. References C11 standard (ISO/IEC 9899:2011): 7.26.5.2 The thrd_current function (p: 383)

Defined in header <wchar.h> wchar_t *wmemchr( const wchar_t *ptr, wchar_t ch, size_t count ); (since C95) Locates the first occurrence of wide character ch in the initial count wide characters of the wide character array or integer array of compatible type, pointed to by ptr. If count is zero, the function returns a null pointer. Parameters ptr - pointer to the wide character array to be examined ch - wide character to search for count - number of wide c

Defined in header <string.h> size_t strcspn( const char *dest, const char *src ); Returns the length of the maximum initial segment of the null-terminated byte string pointed to by dest, that consists of only the characters not found in the null-terminated byte string pointed to by src. The behavior is undefined if either dest or src is not a pointer to a null-terminated byte string. Parameters dest - pointer to the null-terminated byte string to be analyzed src

Defined in header <stdio.h> int fclose( FILE *stream ); Closes the given file stream. Any unwritten buffered data are flushed to the OS. Any unread buffered data are discarded. Whether or not the operation succeeds, the stream is no longer associated with a file, and the buffer allocated by setbuf or setvbuf, if any, is also disassociated and deallocated if automatic allocation was used. Parameters stream - the file stream to close Return value ​0​ on success,

Defined in header <time.h> typedef /* unspecified */ clock_t; Arithmetic (until C11)Real (since C11) type capable of representing the processor time used by a process.
